Overview
The HunterLab ColorQuest XE is a benchtop spectrophotometer engineered for precision color measurement across reflective, transmissive, and translucent samples in industrial quality control and R&D environments. Operating on the CIE-standard d/8° geometry with integrated sphere optics, it delivers traceable, repeatable color data compliant with ISO 11664, ASTM E308, and CIE 15:2018. Its pulsed xenon lamp provides stable, daylight-simulated illumination (D65 equivalent) without spectral drift or warm-up delay—eliminating lamp aging effects common in tungsten-halogen systems. The instrument measures CIELAB (L*a*b*), ΔE*ab, Yellowness Index (YI E313), Whiteness Index (WI CIE/ASTM E313), APHA/Pt-Co, Hazen, Gardner, Saybolt, turbidity (NTU), opacity, translucency, and lightness (L*)—all derived from full-spectrum reflectance/transmittance data acquired at 10 nm intervals across the visible range (400–700 nm). Designed for operational continuity in high-throughput labs and production floors, the ColorQuest XE supports both routine pass/fail evaluation and advanced color formulation workflows.
Key Features
- d/8° integrating sphere optical geometry with specular component included (SCI) and excluded (SCE) modes—enabling independent assessment of surface gloss influence on color perception
- Pulsed xenon light source with >1 million flashes lifetime; no routine lamp replacement required and no warm-up time needed between measurements
- High-stability barium sulfate–coated integrating sphere interior ensures consistent diffuse illumination and minimal photometric decay over time
- Dual-beam optical path design minimizes drift and enhances signal-to-noise ratio, contributing to ΔE*ab repeatability of ≤0.03 (k = 1, 10 readings on white tile)
- Triple-access transmission compartment accommodates bottles, cuvettes, sheets, and irregularly shaped transparent media up to 50 mm thickness
- Ergonomic sample stage with spring-loaded clamp system enables rapid, reproducible positioning of solids—including powders, granules, and textured surfaces—without operator-induced pressure variation
- Front-panel status LEDs provide real-time feedback on measurement mode (reflectance/transmission), calibration state, and communication status
Sample Compatibility & Compliance
The ColorQuest XE accommodates opaque, translucent, and transparent samples—including plastics, textiles, coatings, ceramics, paper, glass, liquids, and pharmaceutical suspensions. It meets ISO/IEC 17025 requirements for laboratory competence when operated under documented SOPs and calibrated per HunterLab’s NIST-traceable protocols. Data integrity complies with FDA 21 CFR Part 11 when used with optional QualiSoft™ software featuring electronic signatures, audit trails, and role-based access control. Instrument inter-instrument agreement conforms to ASTM D2244 (ΔE*ab < 0.15 between matched units), supporting multi-site color standardization across global supply chains. All firmware and calibration files are version-controlled and exportable for GLP/GMP documentation.
Software & Data Management
The ColorQuest XE operates natively with EasyMatch QC software (Windows-based), offering customizable templates for pass/fail tolerancing, batch reporting, SPC charting, and cross-instrument data synchronization. Optional QualiSoft™ adds full 21 CFR Part 11 compliance—including user authentication, change history logging, and immutable data archiving. Spectral data exports in ASTM E2539, CGATS.17, and CSV formats enable integration with ERP/MES platforms (e.g., SAP QM, Rockwell FactoryTalk). Firmware updates are delivered via secure HTTPS channel and validated through digital signature verification prior to installation.
Applications
- Color release testing of raw polymers and masterbatches in injection molding and extrusion facilities
- Batch-to-batch consistency validation for automotive interior trims, architectural glass, and ceramic glazes
- APHA/Hazen color grading of purified water, solvents, and active pharmaceutical ingredients (APIs)
- Whiteness and yellowness quantification in pulp & paper manufacturing per ISO 11475 and TAPPI T485
- Turbidity and haze measurement in beverage and cosmetic formulations per USP <730> and ISO 14782
- Translucency index calculation for medical device packaging films and dental composites
FAQ
What standards does the ColorQuest XE comply with for color measurement?
It adheres to ISO 11664 (colorimetry), ASTM E308 (computation of color coordinates), ASTM D2244 (inter-instrument agreement), and CIE 15:2018 (instrumental colorimetry).
Can the instrument measure both reflectance and transmittance without hardware modification?
Yes—the d/8° sphere configuration and triple-access transmission chamber allow seamless switching between modes using software selection.
Is the xenon lamp user-replaceable, and what is its expected service life?
No lamp replacement is required during normal operation; the pulsed xenon source is rated for ≥1 million flashes, typically exceeding 5 years of daily use in QC labs.
How is instrument-to-instrument agreement maintained across a fleet of ColorQuest XE units?
Units are factory-matched using NIST-traceable standards and supported by HunterLab’s Inter-Instrument Agreement (IIA) protocol, enabling correlation within ΔE*ab < 0.15 per ASTM D2244.
Does the system support automated data export to LIMS or enterprise databases?
Yes—via ODBC-compliant drivers and configurable XML/CSV export schedules in EasyMatch QC or QualiSoft™, with optional OPC UA connectivity for Industry 4.0 integration.
